Abstract (en)
[origin: US4706855A] There is provided, for a container having a cylindrical outlet, a one-piece deformable dispensing closure in the form of a cap including a circular end wall having a depending peripheral skirt for securing it to the outlet. The end wall includes a scoreline which defines a segment intersecting a portion of the end wall. A complex hollow seal, positioned and sized for insertion into the container outlet, depends from the inner surface of the end wall. The seal also includes a tapered external lip for forming a partially releasable seal with the internal surface of the container outlet. There is a dispensing opening through the end wall. When inward pressure is exerted on the outer surface of the end wall a portion of the end wall within the scoreline is moved inwardly, moving with it a portion of the seal and tapered lip which is in registration therewith. This serves to release the moved portion of the tapered lip from its sealing relation with the internal surface of the container outlet, while the portion of the seal and tapered lip which are outside of the scoreline remain in sealing relation with the outlet. When inward pressure on the end wall is terminated the inwardly moved portion of the end wall and seal move outward and return the moved portion of the tapered lip to its normal sealing relation with the outlet. A modified form of the closure which is lockable and child resistant is also taught.
